ICE-CAN. 7

residing at \Varren, in the county of .Trum-- bull and State of Ohio, have invented certain new and useful Improvements in Ice- Cans, of which the following is a specification.

My invention relates to improvements in the construction of ice cans of that class in which the side walls of the can are united to its bottom by an external folded seam; and the objects of my improvements are to strengthen the bottom corners of the can and to reduce the number of constructive operations and, thereby, the manufacturing cost and selling price of ice cans.

I am aware that cylindrical tanks and stamping a circular bottom with seamless turned up outer walls to form receiving pockets for the end of the cylindrical side For compactness in shipping, both the ice cans and the ice made in them, how: ever, it is desirable and practically a commercial necessity to make the cans nearly parallelepiped in form, with quadrilateral faces and ends. To form a quadrilateral bottom with folded up edges has necessitated the slitting of the corners of the metal plate, thereby making the lower corners of the cans the weakest parts, whereas they should be the strongest parts of the can.

I have devised a way to provide the necessary metal to make the corners of the cans bottom equally as strong as the rest of the can, without additional construction cost.

I attain these objects and results by the mechanism illustrated in the accompanying drawing, in which Figure 1, is a plan of one corner of a rectangular sheet of metal. Fig. 2, is a perspective of the same after the first operation. Fig. 3 is a perspective of the same after the second operation. Fig. 4 is a perspective from the same point of View after the third operation and Fig. 5 is a perspective of a lower corner of the completed ice can,

broken away.

Similar characters refer to similar parts throughout the several views.

The leaves 3, 3, are then bent upward, as shown in Fig. 4, forming pockets, 5, 5 Fig. 4, and the four walls 6, 6 of the ice can, are seated in said pockets. Thereupon the strips 4, 4, and the leaves 3, 3 are hammered or pressed tightly against the walls 6, 6, and held by rivets 7, 7. The tongues 8, 8 are then pressed tightly together so as to clasp the corner,"'9, of the ice can walls 6, 6; with the result that the four corners of the bottom of the ice can are completely metal covered, and the vacuities necessarily .leftat said corners, prior to my invention, are avoided. The walls, 6, 6; leaves 3, 3; edges 4, 4 and tongues 8, 8 are then soldered together with a resulting can having as much metal at its lower corners as at any other place or places.

2. In a sheet metal vessel, the combination of a sheet metal body of rectangular cross section, and a rectangular sheet metal bottom portion, said bot-tom sheet cut away at the corners, and the side portions intermediate thereof folded along double parallel lines to provide inner and outer flanges, said flanges being folded and providing a channel to receive the end wall of the vessel I body, and providing a vessel supporting rim, and the adjacent edges of said flanges meeting and forming a closed seam, substantially as described.
